strategy is operationally simple and scalable and tolerates various functional groups undermild reaction conditions. Notably, an aldehyde and aryl-2-quinoline-2-yl-ethanol intermediate are involved in the catalytic reaction mechanism. The utility of the present procedure is demonstrated through a facilesynthesis of the antifungal drug (E)-2-(2-(pyridin-4-yl)vinyl)quinoline.

Regiospecific C–N photocyclization of mono- and bis-styryl-substituted N-heterocycles was investigated. We demonstrated that the C–N regiospecificity of the photoinduced electrocyclization is a general feature of ortho-styryl-substituted N-heterocycles comprising one and two nitrogen atoms. This phototransformation provides a straightforward synthesis of the pharmaceutically important benzo[c]quinolizinium
研究了单-和双-苯乙烯基取代的N-杂环的区域特异性C–N光环化。我们证明了光诱导电环化的C–N区域特异性是包含一个和两个氮原子的邻苯乙烯基取代的N-杂环的一般特征。这种光转化提供了药学上重要的苯并[ c]的直接合成。]喹啉鎓阳离子及其氮杂类似物。值得注意的是,双苯乙烯基衍生物仅经历了一次环化,而第二个苯乙烯基片段仍未参与环化过程。单苯乙烯基衍生物的光环化产物插入小胸腺DNA(ct DNA),而双苯乙烯基衍生物的光环化产物具有与ct DNA的混合结合机制。该结果可用于开发基于苯并[ c ]喹啉鎓衍生物的新型靶向DNA的化学疗法。

The corresponding cyclobutane derivatives were synthesized with yields of up to 57%. The efficiency of this photoreaction depends on the nature of the heterocyclic residue and the concentration of heterostilbenes. The mild reaction conditions and the absence of additives facilitate the reaction. This work provides a convenient and gentle method for the preparation of cyclobutanes.
